SHEET 0B0! 12 PATENTED U58 1 8 I975 SEE? 12 0F 12 APPARATUS FOR WRAPPINGROLLS OF MATERIALS This invention relates in general to a method andapparatus for covering textiles and other sheet materials which arecustomarily wound on a web winding machine to provide what may bereferred to as a goods roll." In one specific aspect, the invention isconcerned with a method and apparatus for applying a protective wrappingaround a goods roll at a point where the web winding operation has beencompleted and the goods roll is ready to be doffed.

It is now customary to apply a wrapping of paper or other sheet materialto a goods roll after it has been removed from the web winding machine.Usually the wrapping operation is done manually and it is found thatrolls handled in this way cannot be wrapped as quickly as they can beproduced by the web winding machine, and thus production is slowed andwinding is limited to the wrapping operation. Furthermore, the sheet maybe subjected to damage in the interval between doffing and applicationof the wrapping.

It is, therefore, a chief object of the invention to cope with theselimitations in the web winding operation and the equipment employed andto provide an improved method and apparatus for applying a wrapping to agoods roll while it is in the web winding machine and before doffing isto take place.

Another specific object of the invention is to devise a wrapperapparatus which can be readily attached to a web winding machine andwhich can be integrated with conventionalweb winding procedures so thata desirable degree of automation is realized in the processing of acompleted goods roll ready for shipment.

Still another object of the invention is to devise a method and meansfor adhesively securing overlapping portions of a wrapper at the time itis passed around a goods roll.

With these objectives in mind, we have conceived of a method of coveringa finished goods roll with a wrapper sheet while the goods roll is stillin rotative movement on winding drums of a web winding machine andpreferably at a point immediately subsequent to cutting the web which isbeing drawn off by the winding drums.

My improved method of wrapping is based on the novel concept ofproviding a flat sheet of wrapping material of a predetermined size,locating the sheet in close proximity to a goods roll just prior to itscompletion, and feeding the flat sheet into the nip of the winding drumsas the Web of textile material is cut off so that the leading edge ofthe wrapping is held between an outermost edge of the goods roll andadjacent surface of the roll and carried all the way around into a fullywrapped position.

The method may also include, in one preferred embodiment, the step ofapplying a band of adhesive to a trailing edge of the flat wrapper sheetand utilizing this band of adhesive to adhesively secure overlappingportions of the wrapper sheet against one another.

In carrying out the method of the invention, we have devised a wrappingapparatus which can be attached at an upper side of a web windingmachine. In its broadest aspect, the wrapping apparatus includes awrapper handling frame, a supply roll of wrapper material, means forfeeding the wrapper material into the frame and cutting off a desiredlength of the material, and means for advancing the cut length of thematerial in a flatwise position into the nip of the goods roll and anadjacent winding drum.

The invention and its other objects and novel features will be morefully understood from a description of the preferred embodiments of theinvention shown in the accompanying drawings in which:

Attention is directed to FIGS. 1 4 of the drawings in which the rollwrapping apparatus of the invention is shown mounted on a conventionalweb winding machine. The roll wrapping apparatus illustrated comprisesone preferred means for carrying out the method of the invention whereina measured length of wrapping is cut off and located around a freshlywound goods roll. However, the method of the invention is not limited tothe apparatus as hereinafter described in detail, and it should beunderstood that other means of carrying out the method steps disclosedmay be utilized.

The principal parts of the wrapping apparatus illustrated include rollmeans for supplying a wrapping material such as a web of paper, plastic,or the like, means for drawing off a desired length of the material andcutting it, and a mechanism for advancing the cut length of materialinto a position in which it can be wrapped around a finished goods roll.

It is intended that our improved roll wrapping apparatus may be utilizedwith any of the well-known forms of web winding machines used in theart. One such form of web winding machine is exemplified by the webwinding structure described in U.S. Pat. No. 3,l67,268, owned by theassignee of the present application, and the invention will behereinafter disclosed in detail with reference to application on thisspecific form of web winding machine.

FIGS. 1, 2 and 3 illustrate the apparatus of the invention combined withportions of a web winding machine M of the three-roll class, having aconstruction generally corresponding to that of U.S. Pat. No. 3,167,268,as shown therein, winding drums W1 and W2 are rotatably supported insuitable bearings in side wall portions of the machine. It is customaryin a web winding machine of the class noted, for a web of textile,plastic or the like, to be drawn off from a supply source and led aroundwinding shell means to start building a goods roll. The shell and thegoods roll being formed are at first supported on primary winding drums.Thereafter, a partly wound roll is transferred so that it is supportedonthe second drum and a third winding drum. Winding then continues untilthe goods roll is completed and ready to be doffed.

In FIG. 5, we have shown diagrammatically a web W, primary winding drumsW1 and W2, a third winding drum W3 and a shell W4 located above the drumW1. Also shown in FIG. 5 in dotted lines, is a fully wound goods roll G,a vertically adjustable cutter blade B and a pneumatic cylinder 131 foractuating the blade B. As will be observed in FIG. 5, the blade B isshown at a point where the goods roll G is ready to be doffed and a cuthas just been made to provide a trailing web edge W5 and a new leadingedge W6 about to be engaged around the shell W4 to start building a newgoods roll. The shell W4 is moved into a position to engage the leadingedge W6 by means of a shell feeding mechanism W7 of well-known nature.

As earlier noted, the method of the invention in one preferred form isdesigned to be carried out in carefully timed relationship to this pointreferred to where a goods roll is fully wound and a web cut is made. Animportant feature of this method is the step of entering a sheet ofwrapping material between the trailing edge W5 and an adjacentperipheral surface of the wound roll G while the latter member is stillrotating and capable of drawing the sheet of wrapping material arounditself, for example, into a position such as that shown in FIG. 16 inthe drawings.

In carrying out this operation, we combine with the conventional windercomponents described above, a

wrapper supplying apparatus which is mounted at the upper side of theconventional winder structure noted in a manner such that one part ofthe apparatus may, at a predetermined point, be moved into a positionimmediately above the winding shell W4 and the blade B in its raisedposition.

Considering this apparatus in further detail, attention is directed toFIG. 6. As shown therein, a sheet S of paper or other material suitablefor use as a wrapping for the goods roll G is supplied from a roll ofsuch material supported at some convenient point near the winder machineM. It will be understood that the supply roll, while not shown in thedrawings, is of conventional nature and may be mounted in a roll standcommonly used for rotatably supporting supply rolls of this nature.

The sheet S is drawn upwardly as indicated diagrammatically in FIG. 6 bymeans of a pair of drafting rolls 6 and 8, received in a bracketstructure 4 mounted at the upper outer side of the machine M asillustrated in FIGS, 2, 3 and 4. Roll 8, as shown in FIG. 1, is drivenby a motor 9 and sprocket 9 chained to an upper sprocket 10 on a shaft12. Also located on this bracket structure 4 in front of the draftingrolls 6 and 8 is an elongated web-supporting brush 14 on a verticallydisposed frame part 14a extending upwardly from the bracket 4 as isbetter shown in FIG. 7. Arranged above the brush 14 and in front of thedrafting rolls 6 and 8 is a cutter blade 16 formed with V-shaped cuttingteeth as indicated in FIG. 7, and being fixed on an arm 13 retatablymounted at 16a for movement downwardly into contact with a section ofsheet S passing across the brush 14 as also suggested in FIG. 6. Thisprovides a means of cutting off a desired length of the sheet materialand it will be noted that the sheet material is firmly supported fromits underside at opposite edges of the brush 14 by means of guide plates18 and 19.

As the sheet material advances through the drafting rolls 6 and 8 andunder the cutter 16, its length may be determined by a machine operator,or we may employ a counter mechanism which may be of conventional typeand connected to the drafting roll drive so as to measure the amount ofsheet material which is travelled through the counting rolls at anyparticular time, or we may employ probe means as hereinafter described.It will be understood that the counter mechanism may be arranged tooperate at a predetermined setting so as to actuate the cutting element16 at a point which will provide a length of sheet material suitable forwrapping a goods roll of any desired size.

As earlier suggested, we may desire to apply an adhesive to a wrappersheet as it is being supplied, although the invention is not intended tobe limited to the use of adhesives. In FIGS. 6 and 9, one form ofadhesive applicator denoted by the numeral 24 is illustrated. As showntherein, the applicator 24 is mounted adjacent to the machine M in avertically adjustable holder 26. The location of the applicator ischosen such that it may overlie one edge of the sheet material S as itleaves the rolls 6 and 8 so that there may be applied a band of adhesive28 indicated diagrammatically at the front left side of FIG. 4. Securingthe adhesive band to another portion of the wrapper will be more fullydescribed at a later point in the specification.

Arranged on the machine M in cooperating relationship with the meansabove-described for furnishing a measured and cut length of wrappingmaterial is an adjustable wrapper frame structure generally indicated bythe arrow F and illustrated in two positions of adjustment in FIGS. 1and 2. This adjustable frame structure F supports a movable beltcarriage and belt assembly for advancing cut lengths of wrappingmaterial in one direction; sensing means for locating cut lengths ofwrapping in a desired position of register with a tinished goods rollsuch that one edge of the wrapping is centered and lies in parallelrelationship to the axis of rotation of the goods roll; and inshoot rollmeans for moving positioned lengths of wrapping material in a rightangular direction into the nip formed by a cut trailing edge of woundmaterial on the goods roll and an adjacent peripheral surface of thisroll.

FIG. 1 illustrates the frame and belt carriage in a position to draw offand locate a cut length of the wrapping material and FIG. 2 illustratesthe frame and inshoot rolls in a position to deliver the cut length intothe nip described.

Considering these parts in more detail, the adjustable frame F comprisesa box-shaped enclosure formed from a plurality of frame elements ofaluminum or other suitable material solidly secured together as bywelding. As shown in FIGS. 1 and 2, the frame elements define arectangular bottom section F1 from which extend upwardly two verticalend sections F2 and F3. Secured between the end sections F2 and F3 is arear side rail F4, a center rail F5 and a cross beam F6. Mounted in thebottom section F1 is a flat wrapper support base portion 32 having asmooth upper surface along which a wrapping material may be received andslidably moved along. Along one edge of the base 32 is an angled chuteportion 32a.

It will be understood that the overall dimensions of the wrappingsupport base 32, as well as the width of the sheet material S to besupported on the base 32, are chosen with reference to the axial lengthand diameter of finished goods rolls to be handled. It will also beappreciated that the width of the sheet material S may exceed slightlythe outer peripheral dimension of a fully wound goods roll in order toprovide for overlapping. In addition, the length of a measured andcut-off wrapping section may exceed appreciably the axial length of arespective goods roll to provide for end folding and sealing, and insome wrapping operations, it may be desired to wind two rollssimultaneously. In such case, the wrapping will be required to be alength to cover the two rolls.

Rotary adjustment of the frame F is carried out by means of stub shafts40 and 42 secured at opposite ends of the bottom section Fl as shown inFIGS. 1 through 6. The stub shafts are rotatably supported in respectivebearing members 52 and 54 solidly secured at upper edges of verticalside portions of machine M. Keyed to shaft 40 is a frame positioning arm44. The arm 44 is connected between a pair of plunger elements 46 and 48of respective fluid pressure-operated cylinders 56 and 58. By means ofthese cylinders under suitable operator control, or in response to asignal from the web winding machine M, the frame F may be held in anormally horizontally disposed position and then tilted into an angledposition at the time a fully wound goods roll is being cut.

The movable belt assembly noted above as being supported in the frame Ffor advancing lengths of wrapping in one direction, includes a carriagestructure of generally rectangular form and denoted by the referencecharacter FC. This carriage structure, as is more clearly shown in FIGS.1, 2, 4, 5 and 8, is suspended on pivoting brackets FCl, FCZ, and soforth, pinned to opposite end sections F2 and F3 of frame F. Thepivoting brackets normally assume a vertically disposed position asshown in FIGS. 1 and 7. They may, however, be retated through a shortarc of rotation, as suggested in dotted lines in FIGS. 7 and 8 by meansof pneumatically actuated plunger FC3 anchored in the frame section F4and pivotally attached to an extension piece FC4 secured at one side ofthe carriage. When rotated into the position shown in FIG. 8, thecarriage, it will be observed, is raised a short distance above the baseelement 32 in the bottom of frame F.

Rotatably supported in one end of the carriage FC in bearing members as67 and 69 is a shaft 68, and at the opposite end of the carriage is asecond shaft 74 similarly supported in bearings. Fixed to the shaft 68are rolls 64 and 66, and likewise, fixed to shaft 74 are rolls 70 and72. Located around the rolls 64 and 70 is an endless driving belt 60 andlocated around rolls 66 and 72 is a second endless driving belt 62.

These roll members and the belts carried by them are driven by a motor76, bolted or otherwise attached to the carriage, as shown in FIG. 4,and having a sprocket assembly 78 chained to another sprocket 80 andshaft 68. Normally the belts 60 and 62 are located in a p0sition toengage against and advance a sheet of wrapping material along the base32 when the carriage PC is in a lowered position. It will be apparentthat the belts will be raised upwardly out of contact with such a sheetwhen the carriage is rotated through a short are of travel by means ofthe plunger FC3. Edges of the belts may be retained by tension rollers86 and 88 suspended on adjustable rods 89 and 90, as shown in FIG. 1 andalso indicated in further detail in FIG. 13. We may also desire to holdthe belts firmly against the sheet material by means of guide strips as82 on hangers 84 and 84a, as shown in FIGS. 1 and 11. The guide strip 82and hanger 84 are also shown in detail in FIG. 12.

In moving a length of wrapping along the frame base 32 by means of themovable belt means described, it may also be desirable, as earliernoted, to provide sensing means for controlling the cut of measuredlengths of material. The sensing means may consist in sensing probes as92 and 94 adjustably supported on slides 96 and 98 on a retaining bar100 fixed along one side of the frame F as shown in FIGS. 1. and 2.Above the bar 100 is an indicator strip 100a utilized for measuringstrips of material and having graduations in inches and fractions ofone-quarter inches to provide a direct length reading. The probe 92 maybe arranged to lie in the path of travel of a sheet such as S3 (FIG. 4)so that when the probe is contacted by the leading edge of the sheet, asignal is given for paper drive to stop and a cut to be made by thecutter 16, activated by fluid cylinder 16b. Thereafter, the belt feed isagain actuated and the cut length of wrapping is advanced to the secondprobe 94, at which point the cut length is centered.

As earlier noted, there may be instances where wrapping is required tobe carried out to cover two rolls simultaneously wound. In this case, wemay take an intermediate cut to separate two lengths, both of which willbe measured and fed into a wound goods roll assembly. For this purpose,we may provide a sensing probe 102 mounted on a slide 104 in the manneralready described. It will be noted that the position of the probe maybe selectively adjusted as required to meet with varying wrapperdimensions required for any given wrapping operation.

With a cut length of wrapping advanced into a position of registrationrelative to the wound goods roll by means of the apparatusabove-described, a final step consists in rapidly moving the cut lengthof wrapping in a direction at right angles to its earlier travel. Thisis required to be done with the adjustable frame F in the tiltedposition shown in FIG. 2 and earlier described as being carried out inresponse to a signal from the cutting mechanism in the machine M.

To accomplish this movement of the cut length of wrapping laterally awayfrom frame F, we have devised a sheet handling mechanism which isconveniently referred to as an inshoot roll assembly. Included in thisinshoot roll assembly is a pair of inshoot rolls 110 and 112 which arefixed on a shaft 114, (FlG.3) rotatably mounted in a movable bearingstructure 116. As shown in FIG. 7, an upper end portion 116a of thebearing structure 116 is pivotally pinned at 1 16b to the verticalsupport ll6c, rigidly secured to an underside of the member F5. At anopposite end portion 116d of bearing structure 116 is pivotally attacheda plunger 118 vertically movable by a pneumatic cylinder 120. When theplunger 118 is raised, the bearing structure is rotated upwardly a shortdistance. Fixed on the shaft 114 at one side of bearing structure 116 isa sprocket gear 122 driven by a chain 124, in turn, driven by a sprocket126 and motor 128. When the motor 128 is activated, it rotates theinshoot rolls and these rolls instantaneously shoot the length ofwrapping laterally along the base 32 and downwardly into the nip pointof the trailing edge W of goods roll G, earlier described. Rotativemovement of the roll G continues and wraps the material around itselfand the band of adhesive 28 overlies and becomes adhesively secured toan adjacent surface of the wrapper. The roll may then be doffed and theends of the wrapper folded and sealed. FIG. 16 illustrates a wrappedroll G1 with a covering edge G2 secured by the band adhesive 28.

In carrying out a typical wrapping operation utilizing the motors 9, 76and 128 together with specific electrical control means and air actuateddevices, we may provide an operator control center which is not shown inthe drawings, but is located at some point closely adjacent to the webwinding machine M, and which will have a switch panel. The air actuatedcontrols are illustrated in the schematic diagram of FIG. 14, and theelectrical controls are illustrated in the wiring diagram shown in FlG.l5.

it should be understood the wrapping operation of the invention iscarried out in combination with operation of an automatic web windingmachine M of the type earlier referred to and described in U.S. Pat. No.3,167,268, and therefore, wrapper controls are located next to thewinder controls for easier wiring into connections. All of thesecontrols are connected to 1 l5 v AC and utilize 80 p.s.i. air supply.

With the air supply open and a line pressure of 80 p.s.i. the fluidpressure actuated cylinders 56 and S8 raise the wrapper frame F to ahorizontal position above the winder and the frame reamins inactive inthis position until such time as the power switch for wrapper controlsis turned on. With the power switch turned on and the movable beltcarriage FC in a down position, the wrapper feed drive will beginfeeding wrapping material, and the wrapper belt drive will carry thewrapper across the frame base 32 until the first probe 92 is disengaged.At this point, the paper is cut and then moved to a centering probe 94whereupon the wrapper stops. While the wrapper is being moved across thewrapper frame a band of adhesive is being applied on the closing edge ofthe paper.

The cut wrapper remains in a horizontal position awaiting the step oftransferring the goods roll G from the first to the second windingposition in the machine M. After roll transfer takes place, the wrapperframe is lowered into the tilted position of FIG. 2 awaiting a signalfrom the cutter 16 to release the wrapper. When the cut occurs, theinshoot wheels instantly advance the cut wrapper into the trailing edgenip as the goods roll rotates and the adhesive band is drawn around intoa sealing position. The wrapped goods roll is then doffed. Thereafterthe wrapper frame F returns to a horizontal position, a new length ofwrapping begins feeding, and the cycle described is repeated.

ln wrapping split materials involving two rolls on a common mandrel, asmay be required in some cases, a probe 102 is used together with thefirst and second probes for determining lengths of two separate sectionsof wrapping. Where a third probe arrangement is mounted on the machineand only a single length of wrapper is required, one probe can bedisconnected by a selector switch, PB-S. In FIG. 17, two wrapped rollsG3 and G4 are shown and illustrate utilizing two cut lengths of wrappermaterial secured in the manner shown in FIG. 16.

In FIG. 14, pneumatic controls indicated therein include a compressedair supply CA, wrapper cutter activator elements PCl, PCZ and solenoidvalve S1; adhesive nozzle operator NO and a solenoid valve S2; inshotsheels activating means 56 and 58 and a solenoid valve S5; and carriagelifting means FC3 and a solenoid valve S6.

FIG. 15 is illustrative of one suitable wiring arrangement for carryingout the method of wrapping of the invention in one preferred sequence ofsteps. Prior to starting the wrapping cycle, a lead edge of the wrappermaterial is moved as closely as possible to the edge of the wrapper base32. The probes are then positioned to deliver sufficient material toclose the ends of a wrapped roll. As earlier noted, this will dependupon cloth width and roll diameter requirements. With the air line open,the power switch P86 is turned to on. Power switch PB6 has one set ofslow-make slow-break contacts permitting activation of two differentsets of relays in sequence. The first set of contacts activate a beltcarriage solenoid S6 through limit switch L-l, closed when wrapper ishorizontal.

With the movable carriage FC down, the length and centering probes 92and 94 may be engaged by the wrapper edge as it advances and thiscompletes grounding curcuit and activates low voltage DC relays R R andR, starting motor 9, belt drive motor 76 and raising inshoot wheels 86and 88 by de-energizing inshoot sheels solenoid S3. The second set ofpower switch contacts will set up wrapper cutter relays R-3 and R-4.Relays R-3 and R-4 will be activated after the wrapper measuring relay Rdrops out (circuits for probes 92 and 94 are broken).

in wrapping and sealing the goods roll with adhesive, a bead of flue orother adhesive is required to be applied along the closing edge of thewrapper, and the adhesive nozzle 24 is required to be properly alignedwith the closing edge of the wrapper. Adhesive may be supplied from atank T-3 pressurized, for example, at 20 p.s.i.g. The nozzle 24 is heldout of contact with the wrapper in closely spaced relationship anddispensing of adhesive is controlled through a time delay R-S which isadjusted to avoid adhesive being dispensed before paper passes under thenozzle 24. Relay R-S is energized in parallel with wrapper measuringrelay R R-5 drops out and de-energizes glue dispensing solenoid 8-2 whenR drops out, therefore adhesive is not applied to the last few inches ofthe covering edge of the wrapper and this prevents any adhesive fromdropping onto the cutter frame.

The wrapper cutter 16 is operated through relays R-2, R-3, and R-4. Whenrelay R is de-energized (and in succession relays R,, R by braking probecircuits) timer circuit R-2 will be energized permitting wrapper feedand belt drive to come to a full stop before the wrapper is cut. Thisprevents the wrapper from being forced into the cut support by an idlingfeed motor.

The operator then adjusts timers R-3 and R-4 to minimum required fordrives to stop. Timer R-2 is adjusted to reenergize drive supportthrough relays R R R, and R,,.. Relays R and R are tied in with groundedprobes and will energize wrapper belt drive motors via relay R Relays RR-1 and R-9 are tied in with wrapper drive motor 9. Relays R-9, R-10 andR-ll are probe safety cut-out relays used to insure that only one probeat any one time can energize motor 9 and belt drive motor 76.

With belt carriage down and probe circuit energized, R-9 is energized,positively cutting out R-ll and completing motor 9 circuit via R-l.Timer R-lll) is used only to eliminate race between relays R9 and R-l 1.With relay R-9 de-energized, R-9 will drop out and pull in R-l 1. WithR-ll energized, the second probe is locked out from the circuit,therefore relays R-9 and R, cannot be re-energized until the wrapper isremoved and the table returned to horizontal. For the same reasons, themotor 9 circuit is locked out until the table returns to a horizontalposition. Relay R-12 is used to hold belt carriage down against wrapperproviding additional support for the wrapper while the frame is in anangled position awaiting wrapper transfer. R-lZ is held energized viaN/C contacts on L-7 (first jaw down safety) limit switch. Relay R--l3separates signal from L-7 to R-8 and 12-6 timeers permitting each topull in and drop out in sequence.

Release ofa cut wrapper length into the goods roll is achieved through asignal from the cloth-cutting mechanism and the wrapper release drive128. Actual release signal is controlled through relays R-6 and R-8.When a cut signal is given by automatic controls, relays R-6 and R-8 areenergized through N/O L-7 cut safety limit switch. R-6 starts a timingsignal and inshoot drive motor 128 supplying the initial momentum forwrapper release and for timing out lifts inshoot wheels releasing thewrapper. R-S delays actual out until wrapper is released by R-6. Timingrelays R-S is the only relay that will have to be adjusted to compensatefor changing line speed. All other relays can be pretimed, set, and donot have to be retimed unless replaced.

From the foregoing description, it will be apparent that we havedisclosed an improved method and apparatus for applying a wrappingmaterial around a wound goods roll. A preferred form of wrappingmaterial may be paper, but such materials as plastic and othersubstances may be employed. The use of a band of adhesive, althoughproviding one convenient means of sealing a closing edge of a wrapper isnot, in all cases, necessary, and it may be desired to use sealing tape,heat sealing or the like to secure the wrapper. The folded ends may alsobe secured by sealing tape.
